TERRY, 33., or DENVER, co'LoRAno, ASSIGNOR, BY MESNE assrcivmnnrs, TO THE GARDNER-DENVER COMPANY, 01' QUINCY, ILLINOIS, A CORPORATION OF DELAWARE AIR CLEANER Application filed January 7, 1927. Serial No. 159,658.

In pneumatically operated tools, particularly those of the portable type such as rock drills, pavement breakers and the like, difliculty is often experienced through the clog- 5 ging up of the moving parts by any dustand sediment carried into the tool by the motive fluid.

The object of the present invention is to provide a sediment collector of a simple,

novel and effective character that can be put directly in the flexible hose line that conveys the air or motive fluid to the tool, said instrument being readily movable about and permitting the free movement of-the hose as the tool is moved from place to place.

In the accompanying drawings:

Figure 1 is a side elevation of one embodiment of the invention,

Figure 2 is a longitudinal sectional view therethrough,

Figure 3 is an end elevation of the inlet end-of the device,

Figure 4 is a cross sectional view on the line 4-4 of Figure 1,

Figure 5 is a side elevation of a modified form of construction,

Figure 6 is a longitudinal sectional view therethrough,

Figure 7 is an end elevation of the outlet end of the device shown in Figures-5 and 6.

Figure 8 is a view showing the device in place in an air line. Referring first to Figures 1-4 inclusive, the collector or trap comprises an outer casing 9 of elongated form, and preferably receiving chamber 15, preferably made of walls that are integral with the casing. Two

substantially circular in cross section, so-

of the opposite chamber walls, designated 16, are spaced from the casingwalls, as shown in Figure 2, thus providing passageways 17 on opposite sides of the chamber affording communication between the inlet nipple 10 and the outlet nipple 12. The

other opposite side walls of the chamber are formed by the corresponding casing walls which will be clear by reference to Figure 4. Through these-Wall's are formed cleanout openings 18 that are normally closed by removable plugs 19 threaded thereinto. The rear end wall 20 of the chamber is' preferably curved, and the front end is'provided with an inwardly extending nipple 21 pierced by an inlet. opening or passageway 22, the inlet nipple 21 constitutin a baflle or retainer for sediment entering t e chamber 15.

In usin the device, it. is preferably placed in a hose 'ne, as shown in Figure 8, wherein a section of said hose line, designated 23, for conducting motive fluid as air, is connected to the inlet nipple 10, while another hose line section 24 connected 'to: the outlet nipple 12 is connected to a drill, as 25. The air supplied b the hose section 23, enters the casing 9 t rough the nozzle 14, and being deflected by the adjacent end of the chamber, passes around said chamber, thence out through the nipple 12 and is carried by the hose section 24 to the tool 25. There is probably no material movement of air in the chamber 15, but it has been found that the momentum of moving particles of'solid material passing through the nozzle 14 will carry the same through the opening 22 and the nipple 21 alined with said nozzle, so that such solid particles will be deposited in the chamber 15 and will not be carried out of the same. The air passing to the tool is thereby materially freed from particles and the danger of interference from such particles is thus obviated. Whenever necessary the chamber can be cleaned of accumulation by taking out one or both plugs 19. This 7 device, it will be noted, is small in size, and

it can readily roll laterall as the hose moves, either while the tool 1s in operation, or is being moved from place to place. This rolling action is not only secured by reason of the external confi uration of the casing, but also by reason 0 the fact that the axis of the nipples constitutes an axis on which the casing may turn.

The structure may also be used wherethere is a common air supply to a plurality of tools. Thus in Figures 5, 6 and 7, the casing 9 is of substantially the form of the first described structure, except perhaps slightly larger in form. It is provided at one end with a central single inlet nipple 10, but has at its opposite end a pair of outlet nipples 12. The chamber, designated 15, is constructed substantially the same as that above described, except that it is connected with the rear end wall of the casing 9 by a partition 20 that separates the nipples 12 and also separates the rear ends of the passages 17", so that each leads to a single nipple 12. This structure has the same advantageous features as that first described, in that it can be coupled up to a supply hose line and branches lead there-. from through flexible conduits to a plurality of tools. It can, however, roll and swing readily as these tools move with respect to each other and is thus usable with drills and other devices that are portable and are employed in confined places.

From the foregoing, it is thought that the construction, operation and many advantages of the herein described invention will be apparent to those skilled in the art, without further description, and it will be understood that various changes in the size, shape, proportion and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

What I claim, is:

1. In a collector of the character set-forth, the combination with a casing having an in let at one end and an outlet at its other end,

of a sediment receiving and holding cham ber housed wholly within the casing and having portions spaced from the walls to provide means for the passage of the fluid to be cleaned from the inlet to the outlet, said chamber having a sediment receiving mouth disposed in opposition to the inlet and in spaced relation thereto.

2. In a collector of the character set forth, the combination with a casing having an inlet at one end and an outlet at its other end, said casing being capable of rolling, of means for connecting a hose line to the inlet and a hose line to the outlet, a sediment receiving and holding chamber housed wholly by the casing and having an inlet facing the casing inlet, said chamber having portionsof its walls spaced from the casing walls to afford communication between the inlet and the outlet, said ,casing having a clean-out opening in one of its side walls and in communication with the chamber, and a detachable closure for the opening.

3. In a collector of the character set forth, the combination with a casing having an inlet and an outlet, of a sediment receiving chamber located in and housed by the casing, said chamber being closed save for an inlet facing the casing inlet, a sediment retaining nipple surrounding the chamber inlet and projecting into the chamber, and a nozzle through which the casing inlet opens, said nozzle projecting into the casing toward and contiguous to the chamber inlet.

4. In a collector of the character set forth, the combination with an elongated tubular casing having an inlet nipple at one end for the connection of a hose and an outlet nipple at the other end for the coupling thereto of a hose, said casing being capable of rolling with said nipples substantially as an axis of rotation, of an elongated tubular sediment receiving chamber contained wholly within the casing and having an open receiving mouth in opposition to the inlet of the casing, said chamber having a clean-out opening through the casing, and a removable closure for the clean-out opening.
